Curiosity celebrates ten years on Mars
Sometime today the rover Curiosity will celebrate its tenth anniversary on Mars. The oblique graphic of Gale Crater above, first released by the science team shortly before landing in 2012, has been further annotated with a red line to show the rover’s journey since then. As noted by Scott VanBommel, Planetary Scientist at Washington University, today on the science team’s blog:
As we the science and engineering teams have aged this last decade, so has Curiosity. The toll of ten years and nearly 28.5 km [17.7 miles] of Mars driving shows with every MAHLI wheel imaging activity, with less energy available for a plan, and with aging mechanisms. This is the life of a Mars rover. Spirit and Opportunity were no different, yet they persisted and paved the way scientifically and technologically for the rovers of today. Curiosity has made numerous scientific discoveries during these ten years, emphasized by the over 500 science team publications, with many more ahead as we continue our ascent and exploration of Gale crater and Mount Sharp.
I look forward to the next ten years.
Despite that aging, Curiosity’s general condition appears quite excellent, with its wheels the greatest concern but generally holding up. Based on the last ten years, the rover is likely to remain operational for at least ten more years, if not longer.
In the more immediate future, the rover is only days away from getting its first good look down into Gediz Valles, that canyon on the graphic above that it has been traveling towards since day one.
A good review of five of Curiosity’s biggest discoveries using its sample analysis instrument can be found here.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

A truly remarkable machine, but it’s going to take us a long time to explore Mars at an average of 0.000202 mph. We need boots on the ground, or at least rovers guided by people in orbit to eliminate the light speed delay. I hope Elon can somehow pull off his Mars colonization plans.

Although this is true in general, we have lubricants that will work in vacuum and in the cold. There are other methods of reducing friction and wear between moving parts, too. Our martian rovers demonstrate our ability to overcome the general case for lubricants.
